Unnamed sources tell the Washington Post that the findings were referred to the U.S. attorney’s office in Washington, D.C., to determine whether a federal prosecution is warranted.

The Post says the referral “occurred some time ago” and it’s not clear how the U.S. attorney’s office responded.

Horowitz had found that McCabe lied four times to the FBI director or investigators, including three times under oath. The alleged inaccurate statements were made during a probe into whether McCabe authorized a leak to the Wall Street Journal about an investigation involving the Clinton Foundation.

The intent of the leak was to rebut a narrative that questioned McCabe’s impartiality in overseeing FBI investigations involving former Secretary of State Hillary Clinton, according to Horowitz’s report.

McCabe has said he was authorized to share information with reporters, and he answered questions “as truthfully and accurately” as he could “amidst the chaos” surrounding him.
